There is no school where students do not argue and resolve conflicts among themselves. To resolve entrenched situations, mediation is necessary - ideally by peers as mediators. This booklet offers a tried-and-tested 5-day program for selecting, training, and supervising student mediators. With clear daily plans and detailed instructions for each training step, you can guide the aspiring mediators confidently and systematically through the training week. The material covers all four phases of mediation - introduction, clarification, solution, agreement - and includes numerous communication exercises and role plays, enabling the student mediators to successfully apply what they have learned after the project week. Two practical reports from teachers who have implemented student mediation at their school using this concept complete the booklet.
